SUSPENDING DEVICEFOR ELECTRIC CONDUCTING-WIRES.

SPECIFICATION forming part of Letters Patent No. 430,926, dated June 24, 1890.

Application filed January 28, 1890. Serial No. 837,795. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM M. DAVIS, a citizen of the United States, residing at East WVeymouth, in the county of Norfolk and State of Massachusetts, have invented a new and useful Suspending Device for Electric Conductingires, of which the following is a specification.

This invention relates to devices for suspending the conducting-Wires for electric railways; and it has for its object to provide a device by means of which the said conducting-wires may be suspendod and supported in such a manner as to present a perfectly smooth and unbroken surface for the trolleywheel to travel upon, thereby avoiding the jumping and sparking of the trolley-wheel, which invariably ensues where irregularities occur in the track-wire or conducting-wire.

My invention, with these objects in view, consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective view of a suspending device embodying my improvement, showing a piece of the conducting-wire in position therein. Fig. 2 is a longitudinal vertical sectional view of the same. Fig. 3 is a perspective View showing the parts of the device separated from each other.

Like numerals'of reference indicate like parts in all the figures.

1 designates the upper part or body of my improved suspending device, which consists of a suitably-shaped block, which may be approximately triangular in outline, as shown in the drawings hereto annexed, and which is provided in its under side with a V-shaped recess 2, the ends of which are grooved, as shown at 3, said groove extending to the extreme ends of the under side of the block 1.

4 designates a supporting-block adapted to be fitted in the recess 2, and having its upper sides grooved, as shown at 5, the ends of said groove terminating in the knife-edges 6 at the lower corners of the supporting-block. The grooves 3 and 5 in the recess 2 and the supporting-block 4. together serve to accorn modate the conducting a wire. The latter, which is designated by 7, is provided at the point where it is to be adjusted in the hanger with a bent V-shaped portion 8, adapted to fit in the groove provided for its reception. This bend may be formed upon the wire prior to mounting it in the hanger, or it may be formed by forcing it into the recess 2 of the block 1 by forcibly driving the supportin g-block 4 against it. The supporting-block, when adjusted in the recess 2, is secured by means of a transverse bolt 9, which is pref erably made tapering, as will be seen by reference to Fig. 3 of the drawings.

It is obvious that the parts of my invention are to be made of conducting material, and the several parts may either be cast or otherwise formed in any suitable well-known manner.

The operation of my invention and its advantages will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed.

The block 1 is provided near its upper end with a transverse perforation to enable it to be conveniently suspended from an insulator, or from any suitable support. The wire, it will be seen, is practically supported by resting upon the upper side of the block 4, and the'ends of the latter are tapered to knifeedges, as shown, thus forming practically a smooth and unbroken continuation of the conducting-wire at the point where the latter is suspended.

The construction of the device is simple and inexpensive, and by its use soldering is avoided at the points where the wire is suspended, and smooth and perfectly -regular joints are formed which will in no wise interfere with the passage of the trolley wheel.

Having thus describedmy invention, what I claim is-- 1. A suspending device for electric conducting-wires, comprising a suspending-block and a supporting-block, the latter adapted to be seated in a recess in the former, substantially as and for the purpose set forth.

2. A suspending device for electric conducting-wires having a supporting block adapted to support a bent portion of the wire, and haw ing its ends tapered to knife-edges, so as to form practically an unbroken continuation of the conducting-Wire, substantially as herein set forth.

3. A suspending device for electrical conducting-wires, comprising, mainly, a supporting-block having a straight or unbroken lower edge and provided in its upper side or edge with a groove, the ends of which are tapered v to knife-edges at the ends of the block, said block being adapted to engage and support a bent portion of the conducting-Wire, the body of which is flush with the lower edge of the said supporting-block, substantially as set forth.

4. A suspending device for electric conducting-wires, comprising a suspending-block hav ing a V-shaped recess in its under side, a V- shaped supporting-block grooved in its upper sides and tapered to knife-edges at its ends, and a tapering connecting bolt extending transversely through said suspending and supporting blocks, substantially as set forth.

5. A suspending device for electric conductf with an upper suspending-piece adapted for receiving the conducting-Wire on its under side and holding said wire down in a direct plane with said supporting-block at both ends of same, and a suitable bolt for clamping the whole together, as set forth.

In testimony that I claim the foregoing as l my own 1 have hereto afiixed my signature in presence of two witnesses.
